Why it matters
New GPU partitioning controls and Rubin-architecture preview support let teams start porting and isolating workloads ahead of hardware availability and in shared container environments.
Key quotes
“CUDA Toolkit 13.4 adds functional support for the NVIDIA Rubin architecture (compute capability 107) as a preview, enabling developers to begin porting applications before CUDA support for Rubin reaches general availability in a future release of the CUDA Toolkit.”
“In benchmark results on an NVIDIA Blackwell GPU, the new cub::DeviceScan::Sum implementation reaches up to 92% memory-bandwidth utilization (from up to around 50% in a previous implementation) across the tested data types.”
“CUDA SDK installers no longer bundle the NVIDIA driver.”
